Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864, Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating the law of mass action, which states that the speed of a chemical reaction is proportional to the quantity of the reacting substances.

Writing Rate Laws of Reaction Mechanisms Using The Rate Determining Step - Chemical Kinetics
This chemistry video tutorial provides a basic introduction into reaction mechanisms within a chemical kinetics setting. It explains how to write the rate law expression for a reaction mechanism. A reaction mechanism consist of a series of elementary steps or elementary reactions whose rate law can be written from its molecularity - that is from the coefficients of the balanced reaction. The rate of a reaction mechanism is completely dependent on the slow step or the rate-determining step. This video explains how to substitute an intermediate when writing rate law expressions. It contains plenty of examples and practice problems.

The average and instantaneous rates of reaction are concepts used in chemistry to describe how the concentration of reactants or products changes over time.
Average Rate of Reaction
The average rate of reaction is calculated over a specific time interval. It is defined as the change in concentration of a reactant or product divided by the change in time. The formula for the average rate can be expressed as:
{Average Rate} = Delta [{Concentration}]/{Delta t}
Where:
Delta [{Concentration}]) is the change in concentration (mol/L) of the reactant or product.
Delta (t) is the change in time (usually in seconds).
This gives an overall view of how fast the reaction occurs over that period.

The average and instantaneous rates of reaction are concepts used in chemistry to describe how the concentration of reactants or products changes over time.
Average Rate of Reaction
The average rate of reaction is calculated over a specific time interval. It is defined as the change in concentration of a reactant or product divided by the change in time. The formula for the average rate can be expressed as:
{Average Rate} = Delta [{Concentration}]/{Delta t}
Where:
Delta [{Concentration}]) is the change in concentration (mol/L) of the reactant or product.
Delta (t) is the change in time (usually in seconds).
This gives an overall view of how fast the reaction occurs over that period.
Instantaneous Rate of Reaction
The instantaneous rate of reaction, on the other hand, refers to the rate at a specific point in time. It is determined by taking the derivative of the concentration with respect to time at that moment. Mathematically, it can be expressed as:
{Instantaneous Rate} = d{Concentration} /{dt}
Where:
d[{Concentration}]/{dt} ) represents the derivative, indicating how the concentration changes at a specific moment.
To approximate the instantaneous rate during a reaction, you can find the slope of the tangent line to the curve of concentration versus time at a specific point on a concentration-time graph.
Summary
Average Rate: Calculated over a time interval, gives a general rate of reaction.
Instantaneous Rate: Calculated at a specific moment, gives the rate of reaction at that instant.
Both concepts are crucial for understanding chemical kinetics and how reactions progress.

This chemistry video tutorial provides a basic introduction into reaction mechanisms within a chemical kinetics setting. It explains how to write the rate law expression for a reaction mechanism. A reaction mechanism consist of a series of elementary steps or elementary reactions whose rate law can be written from its molecularity - that is from the coefficients of the balanced reaction. The rate of a reaction mechanism is completely dependent on the slow step or the rate-determining step. This video explains how to substitute an intermediate when writing rate law expressions. It contains plenty of examples and practice problems.

The average and instantaneous rates of reaction are concepts used in chemistry to describe how the concentration of reactants or products changes over time.
Average Rate of Reaction
The average rate of reaction is calculated over a specific time interval. It is defined as the change in concentration of a reactant or product divided by the change in time. The formula for the average rate can be expressed as:
{Average Rate} = Delta [{Concentration}]/{Delta t}
Where:
Delta [{Concentration}]) is the change in concentration (mol/L) of the reactant or product.
Delta (t) is the change in time (usually in seconds).
This gives an overall view of how fast the reaction occurs over that period.
Instantaneous Rate of Reaction
The instantaneous rate of reaction, on the other hand, refers to the rate at a specific point in time. It is determined by taking the derivative of the concentration with respect to time at that moment. Mathematically, it can be expressed as:
{Instantaneous Rate} = d{Concentration} /{dt}
Where:
d[{Concentration}]/{dt} ) represents the derivative, indicating how the concentration changes at a specific moment.
To approximate the instantaneous rate during a reaction, you can find the slope of the tangent line to the curve of concentration versus time at a specific point on a concentration-time graph.
Summary
Average Rate: Calculated over a time interval, gives a general rate of reaction.
Instantaneous Rate: Calculated at a specific moment, gives the rate of reaction at that instant.
Both concepts are crucial for understanding chemical kinetics and how reactions progress.

Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864, Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating the law of mass action, which states that the speed of a chemical reaction is proportional to the quantity of the reacting substances.
